A slick animation with a sweet concept, especially if you like video games. For the ones who have no idea what it is about apart from knowing it's something to do with video games (like me before I watched it...), then the movie takes place in an arcade, and an arcade character (the titular Ralph) journeys from one arcade game to another (they are connected) on an adventure. The animation is great, it's bright and colourful and visually pleasing. The plot is decent but it's nothing terribly special. The thing that elevates this movie is the many video games references scattered. Mainly, the hard hitting references are towards the beginning of the movie and you freak out when you see the likes of Bowser and Sonic appearing, not just as a side reference but as a cameo with dialogue. I didn't find most of the movie to be extremely laugh-out-loud funny, but there were many enjoyable moments and one or two hilarious gags. A lot of the humour relies on puns, which isn't that bad in execution. There were some dark-ish themes and the antagonist was somewhat freaky at the end. This travelling between worlds is the perfect concept for an actual video game, the nostalgia would be massive (kinda like the Kingdom Hearts series of games, but covering a lot more distinct game franchises). Anyway, a solid movie.
